Free Practice Questions for VMware 3V0-24.25 Exam

Answer : A

The problem describes demand spikes where capacity exists, but the application cannot meet demand---this typically indicates the cluster needs toscale out(more nodes/pods) automatically when load increases. In VCF 9.0, VKS supportsCluster Autoscaleras an optional package and specifically calls out improvements: ''Cluster Autoscaler supports scaling from zero or to zero... You must have the autoscaler standard package installed.'' This directly supports optionA(install cluster autoscaling) as the mechanism to dynamically add capacity during peak events and reduce it afterward, optimizing cost and operations while meeting bursts. A load balancer (including Foundation Load Balancer) helps distribute traffic acrossexistingendpoints, but it does not create new compute capacity when pods are pending due to insufficient nodes. Similarly, installing Contour relates to ingress (routing inbound traffic) and is not, by itself, a capacity scaling solution. Oversubscription is a risky workaround that can degrade performance and does not provide targeted, policy-driven elasticity. Therefore, enablingcluster autoscalingis the correct way to address burst demand when underlying resources are available.

Answer : C, E

VCF 9.0 positions VKS clusters as Kubernetes-native environments where platform teams install and manage ''standard packages'' and add-ons. In VCF Automation's VKS overview, VMware states that a set of packages is automatically included with a VKS cluster, includingkapp-controllerandsecret-gen controller. These components are part of theCarveltoolchain used for packaging and deploying applications/configuration in a Kubernetes-friendly, declarative way.

In addition, the VCF 9.0 CLI ''package'' workflows explicitly supportytt overlaysduring package installation/updates (for example, --ytt-overlay-file and --ytt-overlays), which are configuration mechanisms associated with Carvel-based packaging workflows.

Helmis the other widely used Kubernetes package manager for installing and configuring applications through charts and values, and is commonly used by DevOps teams on Kubernetes clusters such as VKS for app deployment and configuration management. By contrast, Fluent Bit is a log shipper, Multus is a CNI multiplexer, and Grafana is a visualization tool---none are package management tools.

Answer : A

In VCF 9.0, ingress is described as part ofVKS cluster networking. The documentation's VKS Cluster Networking table lists''Cluster ingress''and identifies its role asrouting inbound pod traffic. It further clarifies that this function is delivered by athird-party ingress controller, and explicitly namesContouras an example (''you can use any third-party ingress controller, such as Contour'').

That mapping is exactly what optionAdescribes: Contour is deployed to provideingresscapabilities so that inbound requests from outside the cluster can be routed to Kubernetes services and pods according to ingress rules. In other words, Contour is not a storage component (that would align to CSI/CNS/pvCSI), not a node lifecycle manager (that is handled by VKS/Cluster API/VM Service), and not an infrastructure health monitoring tool (that would be metrics/observability tooling). VCF 9.0 positions Contour specifically within theingresspart of the networking feature set, makingAthe correct answer.

Answer : C

In a vSphere Kubernetes Service (VKS) environment, resource management follows aDeclarative Model. When an administrator uses kubectl edit deployment to manually scale a running workload from 5 to 10 replicas, they are modifying thelive stateof the deployment. However, thesource of truthfor a Tanzu Kubernetes cluster in VCF 9.0 is theCluster YAML specificationmaintained by the Cluster API (CAPI) provider within the Supervisor.

If the administrator redeploys the cluster or if the Supervisor's controller performs a reconciliation loop, it refers back to the original configuration file. If that cluster YAML file still defines the replica count as 5, the Supervisor will terminate the 5 'extra' pods to match the desired state defined in the configuration. This is a common administrative pitfall; for changes to be persistent across redeployments or updates in VCF 9.0, the underlying manifest (the 'Desired State') must be updated. Manually editing the live object only provides a temporary change that will be overwritten during the next synchronization or lifecycle event because the cluster YAML file was not updated to reflect the requested increase.

Answer : C

Amulti-zone Supervisorin VCF 9.0 is designed to deliverplatform resiliency and high availability at the vSphere cluster (zone) failure-domain level. The VCF 9.0 documentation states that a multi-zone Supervisor ''leverages three vSphere clusters'' (each mapped to a vSphere Zone) and that these zones are used by both ''workloads and Supervisor management components to deliver high availability,'' exposing ''each cluster as an independent, consumable availability zone,'' resulting in a ''resilient, HA-capable platform.''

This is reinforced in the vSphere Zones guidance: deploying the Supervisor onthree vSphere Zones spreads the control plane VMs across three zones, providing ''cluster-level high availability'' that protects the Supervisor control plane against asingle cluster-level failure(one control plane VM per management zone).

Because VKS (vSphere Kubernetes Service) runs on Supervisor, distributing Supervisor control plane and workload placement across zones improves overall availability of Supervisor services and Kubernetes consumption in that Supervisor instance.
